But why would Nicole allow tattoos painted on her ass and pose like that? It's all part of a coffee table book (titled Culo)celebrating the fine form of women's backsides brought to you by Sean Diddy Combs, Interscope record chairman Jimmy Iovine and the photographer behind the art Raphael Mazzucco.

There are 248 photos in all including Lady GaGa and Irina Shayk and you can see all of the famous ass as of now because the book is in stores!
